It is a bit awkward to have a title for every frame, but not for the one
that holds the table of contents. Allow users to specify a title if they
wish.
Closes#4803
After this commit use `$titleblock$` in order to get what was contained
in `$title$` before, that is a title and subtitle rendered according to
the official rST method:
http://docutils.sourceforge.net/docs/user/rst/quickstart.html#document-title-subtitle. from
With this commit, the `$title$` and `$subtitle$` metadata are available and they
simply carry the metadata values. This opens up more possibilities in templates.
New variable with same name as comparable variable in (proposed) reveal.js template, so that background images can indicated for both presentation formats with one variable.
Removed `--latexmathml`, `--gladtex`, `--mimetex`, `--jsmath`, `-m`,
`--asciimathml` options.
Removed `JsMath`, `LaTeXMathML`, and `GladTeX` constructors from
`Text.Pandoc.Options.HTMLMathMethod` [API change].
Removed unneeded data file LaTeXMathML.js and updated tests.
Bumped version to 2.2.
This file wasn't used in the production of documents. It's supposed to
be a thumbnail of the current document, and we can't actually produce
that ourselves. It turns out that the file contains a nonfree ICC
color calibration file, so the best thing to do would be to remove it
altogether.
Fixes: #4588
Previously this looked in the filesystem, even if pandoc
was compiled with `embed_data_files` (and sometimes it looked
in a nonexistent build directory). Now the bash completion
script just includes a hard-coded list of data file names.
See #4549.
* LaTeX template: Use `pgfpages` package; this is needed for notes on second screen in beamer
* LaTeX template: Add `beameroption` variable in template
The resulting PDF can be verified using the Apache PDFBox preflight app.
```
$ java -jar preflight-app-2.0.8.jar test.pdf
The file test.pdf is a valid PDF/A-1b file
```
Instructions on how to install the ICC profiles on ConTeXt standalone can be found in the wiki: <http://wiki.contextgarden.net/PDFX#ICC_profiles>.
If the ICC profiles are not available the log will contain messages like these
```
backend > profiles > profile specification 'sRGB.icc' loaded from '/usr/local/texlive/2017/texmf-dist/tex/context/colors/icc/context/colorprofiles.xml'
backend > profiles > error, couldn't locate profile 'srgb.icc'
backend > profiles > no default profile 'srgb.icc' for colorspace 'rgb'
backend > profiles > profile specification 'sRGB IEC61966-2.1' loaded from '/usr/local/texlive/2017/texmf-dist/tex/context/colors/icc/context/colorprofiles.xml'
backend > profiles > error, couldn't locate profile 'srgb.icc'
backend > profiles > invalid output intent 'sRGB IEC61966-2.1'
```
and the resulting PDF will not be valid PDF/A:
```
$ java -jar preflight-app-2.0.8.jar test.pdf
The file test.pdf is not a valid PDF/A-1b file, error(s) :
2.4.3 : Invalid Color space, The operator "g" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, The operator "G" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, /DeviceGray default for operator "TJ" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, /DeviceGray default for operator "TJ" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, The operator "g" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, The operator "G" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, /DeviceGray default for operator "TJ" can't be used without Color Profile on page 1
```
However, the PDF will still be generated and the "errors" shown in the log do not break anything.
* Provide `bidi` package's option using `\PassOptionsToPackage`. This avoid clash when `polyglossia` loads it first and then it is loaded again for XeLaTeX when `latex-dir-rtl` defined.
* Adjust test suite for LaTeX template change.
Elements with attributes got an additional `attr` accessor. Attributes
were accessible only via the `identifier`, `classes`, and `attributes`,
which was in conflict with the documentation, which indirectly states
that such elements have the an `attr` property.
Every constructor which accepts a list of blocks now also accepts a
single block element for convenience. Furthermore, strings are accepted as
shorthand for `{pandoc.Str "text"}` in constructors.
Accessing an Attr value (e.g., ` Attr().classes`) was broken; the more
common case of accessing it via an Inline or Block element was
unaffected by this.
This attribute was out-of-sync with the actual version as is mostly
irrelevant in the context Lua filters and custom writers. Use the
global `PANDOC_API_VERSION` instead.
*Pandoc*, *Meta*, and *Citation* were just plain functions and did not
set a metatable on the returned value, which made it difficult to amend
objects of these types with new behavior. They are now subtypes of
AstElement, meaning that all their objects can gain new features when a
method is added to the behavior object (e.g., `pandoc.Pandoc.behavior`).
Clearly distinguish between a type and the behavioral properties of an instance
of that type. The behavior of a type (and all its subtypes) can now be amended
by adding methods to that types `behavior` object, without exposing the type
objects internals.
E.g.:
pandoc.Inline.behavior.frob = function () print'42' end
local str = pandoc.Str'hello'
str.frob() -- outputs '42'
Extending all elements of a given type (e.g., all inline elements) was
difficult, as the table used to lookup unknown methods would be reset
every time a new element of that type was created, preventing recursive
property lookup. This is was changed in that all methods and attributes
of supertypes are now available to their subtypes.
The fields were named like the Haskell fields, not like the documented,
shorter version. The names are changed to match the documentation and
Citations are given a shared metatable to enable simple extensibility.
